Embodiment Construction

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0049] The present invention provides a flexible composite lattice type recyclable double-row pile supporting structure design and construction method. In the supporting structure design, starting from the essence of the foundation pit engineering, the supporting piles are arranged in two rows. The composite design concept introduces the excellent mechanical properties of the traditional space structure into the foundation pit supporting structure necessary for underground development. At the same time, it gives full play to the technical advantages of steel's good mechanical precision manufacturing and on-site assembly standardized production, and the use of mechanical precision manufacturing , The idea of ​​on-site assembly and standardized production. After the design work is com...

Abstract

The invention relates to a design and construction method for a flexible composite lattice type recyclable double-row pile supporting structure. The method comprises the following steps that (1), a front pile row and a rear pile row are constructed; (2), profile steel crown beams are installed; (3), the earthwork is excavated in layers, panels are installed, and polymer grouting is carried out; (4), waist beams and contra-pull connecting rods are installed; (5), the earthwork is excavated vertically, hierarchically and sectionally in turn, the third step and the fourth step are repeated, the earthwork is excavated to the base elevation, and the construction of the flexible composite lattice type recyclable double-row pile supporting structure system is completed; and (6), after the supporting structure completes the use function, the supporting structure can be recycled step by step with the backfilling of a foundation pit. The constructed supporting structure system has the beneficialeffects of more reasonable structural stress, stronger resistance to lateral earth pressure, avoidance of crossing red lines, safety and reliability, quick construction, advanced technology, recyclability, superior economic and environmental protection indexes and the like and has considerable development and application prospects.

Description

Technical field [0001] The invention belongs to the field of excavation and support construction of underground infrastructure such as civil engineering, water conservancy, mining and transportation, and specifically relates to a design and construction method of a flexible composite lattice type recyclable double-row pile support structure. Background technique [0002] Since the founding of the People’s Republic of China, my country’s civil engineering, water conservancy, mining, and transportation infrastructure construction has achieved world-renowned achievements. In the process of underground space utilization and mining of mineral resources, when faced with complex geological conditions, it is often necessary to adopt slope support measures to prevent slope creep, and sometimes the impact of groundwater needs to be considered. With the development of technology, machinery and civil engineering materials in the field of geotechnical engineering, slope support technology has...
